Abstract
The utility model discloses a movable high-voltage switch cabinet powered by double power supplies, which comprises a cabinet body and a breaker handcart arranged in the middle of the cabinet body. Two-lock one-key straight-pull app locks are arranged on the breaker handcart, two app locks are controlled through one app lock key to lock a working position or a test position of the breaker handcart, reliability of the double power supplies is further improved, and an interlocking method is easy to assemble, safe and reliable and strong in mistaken operation resistance.
Description
Technical field
The utility model relates to the High voltage power supply equipment technical field, more particularly, relates in particular to a kind of dual power supply moveable high-voltage switchgear.
Background technology
For improving the reliability of power supply, dual power supply is adopted in important electricity consumption place usually.In dual power supply system, be fail safe and the reliability of guaranteeing to supply power, except mechanical interlocking is set in high-tension switch cabinet, satisfy outside " five is anti-" requirement, also be provided with electrical interlock between two power supplys, make it that power supply of one road power supply only arranged.Existing dual power supply moveable high-voltage switchgear generally is to adopt screw mandrel to advance or retreat circuit breaker cart and control its service position or test position, have only when handcart in the service position or during test position, circuit breaker just can close a floodgate.Because the mechanical interlocking reliability of handcart is relatively low, misoperation makes the circuit breaker cart of two-way power supply be in the service position simultaneously, and makes duplicate supply that the anti-electricity that send take place, and the person and device security are constituted grave danger.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art, provides a kind of security reliability high dual power supply moveable high-voltage switchgear, improves the reliability of circuit breaker cart interlocking, strengthens anti-misoperation property.
For realizing above-mentioned purpose, the dual power supply moveable high-voltage switchgear that the utility model provided is on the circuit breaker cart of existing high-tension switch cabinet, to install one procedure lock, and this procedure lock is that two locks, one key directly pulls out procedure lock.
The utility model is controlled two procedure locks to the procedure lock key through the lock of installation procedure on circuit breaker cart with one, and the service position or the test position of locking circuit breaker cart further improve the reliability that circuit breaker cart is interlocked.Have only when wherein a circuit breaker cart is in test position and just can key be taken off, then key is placed on the tapered end of another procedure lock, lock is opened; Another circuit breaker cart was pushed into the service position, carries out branch, the closing operation of circuit breaker, and key can not be extracted from procedure lock this moment; Therefore can not operate last procedure lock; Thereby guarantee in two circuit breaker carts one when the service position, another just can only guarantee only to have the power supply of one road power supply in test position.This kind interlock method is installed simply, anti-misoperation property is strong.
Description of drawings
Fig. 1 is the front view of breaker compartment in the utility model dual power supply moveable high-voltage switchgear;
Fig. 2 is the left view when circuit breaker is in the service position in the high-tension switch cabinet shown in Figure 1;
Fig. 3 is the left view when circuit breaker is in test position in the high-tension switch cabinet shown in Figure 1.
Among the figure: the 1-cabinet; The 2-bus-bar room; The 3-breaker chamber; The 4-cable vault; The 5-circuit breaker cart; The 6-procedure lock.
Embodiment
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.
Consult Fig. 1 to shown in Figure 3; The utility model dual power supply moveable high-voltage switchgear comprises cabinet 1, and cabinet 1 usefulness metal partion (metp) is separated into bus-bar room 2, breaker chamber 3, cable vault 4 etc.; Said breaker chamber 3 is positioned at the middle part of cabinet 1; Be equipped with circuit breaker cart 5 in it, procedure lock 6 is installed on the circuit breaker cart 5, this procedure lock 6 is that two locks, one key directly pulls out procedure lock.
The operation principle of the utility model is two procedure locks of procedure lock key control, the service position or the test position of locking circuit breaker cart 2 with one.Key can not be extracted when wherein a circuit breaker cart 5 is in the service position, just can key be taken off when only being in test position, operates another procedure lock; Can insert key on the tapered end of another procedure lock this moment, lock opened, and another circuit breaker cart 5 is pushed into the service position; Carry out branch, the closing operation of circuit breaker; Make in two circuit breaker carts one when the service position, another just can only can't be connected with main bus bar in test position; Reach the isolation purpose, guarantee only to have the power supply of one road power supply.
